This tubular turbine generator unit is applicable to the low-head power station which has a head of less than 20m and the diameter of runner is less than 3m. With the merits of considerable and well-going flow, and high efficiency, this unit is perfectly suitable for developing water resources of low head and large flow in the areas of plains, hills and Coastal place.
High specific speed, largest flow and high efficiency, low investment and so on. Compared with the traditional vertical axial units, it has simple structure and larger volume of cross flow, less construction works is needed of and the maintaining is easy as well. With the same capacity, tubular turbine unit has a runner of which the diameter is smaller than the axial tubular unit by 10%-15%, the annual generating capacity is larger by 10% -15%, and the investment costs can be saved than axial of about 20%, its economic benefits is significant.
